Abstract

An applicator in which an applying body consisting of a brush is surely attached to a front barrel to solve a problem that a part of the brush remains stuck inside the front barrel to cause failure of attachment when the applying body is being attached to the front barrel. The applicator includes a front barrel provided on the front end side of a rear barrel, and an applying body formed of a brush with a flange portion at its rear end and arranged inside the front barrel. A receiving part of the flange portion of the applying body and the inner face of the front barrel are in contact with each other in a non-surface contact manner.

First claim

The invention claimed is:

1. An applicator comprising:
a barrel cylinder storing an application liquid in a storage portion in a rear part thereof; and
an applying body, formed of a brush having a flange portion arranged in an interior front part of the barrel cylinder so as to supply the application liquid to the applying body from the storage portion inside the barrel cylinder,
wherein the flange portion of the applying body includes a receiving part; and
wherein an inner peripheral surface of a front end of the interior front part of the barrel cylinder includes a step portion having a level difference and configured with an engagement portion having multiple triangular tops formed at predetermined intervals on the inner peripheral surface of the front end of the interior front part of the barrel cylinder, and bottoms connected along a circumference of the engagement portion such that the receiving part of the flange portion makes point contacts with the step portion on the inner peripheral surface of the front end of the interior front part of the barrel cylinder.

2. The applicator according to claim 1 , wherein the engagement portion is formed with a radial arrangement.

3. The applicator according to claim 1 , wherein the inner face of the barrel cylinder on a front end side of a point at which the receiving part of the flange portion of the applying body abuts an inner face of the front barrel is tapered.

4. The applicator according to claim 1 , wherein an insertion angle of the applying body at a point where the receiving part of the flange portion of the applying body abuts an inner face of the barrel cylinder and on a front end side ahead of an abutment point is less than 45° with respect to an axial direction.

5. The applicator according to claim 1 , wherein the applying body is assembled into the interior front part of the barrel cylinder.
